How to create a Lyra SMS account for use with the payment gateway?

From your Expert Back Office:

Open the Settings > Company > SMS Account Management tab.
The tab is only visible if you have opted for the “Payment order by SMS” or “SMS Notification” service.

To use this service, please contact the the sales administration to enable the necessary functions within your offer.
Enter your Lyra SMS login and password.
I.e. the login and password you chose when you signed up for Lyra SMS.
Enter the default phone number to be notified.
This number will be used to pre-populate any notification rules you may create in the future. If notification rules have already been configured for your shop, the number will not be filled in automatically.
